Hey all. I own a 2008 SS with 156k on the clock. I'm having an issue where I'm not seeing boost, Low end is very punchy, like it usually is, but top end I'm not seeing any boost above 7 or 8 psi. I used to see 16-18 psi of boost on a hard 3rd gear pull. But now I'm not. I am going to replace the lower silicone intercooler hose with an aluminum one from Werks (trans line leaking on hose). So I'm hoping that will help. Just trying to find things to look for.

Oh, vehicle is also equipped with the GM Stage 1 and a Forge BOV. Wires to the map sensors are fine, I checked them myself.
